Right, so just in case I'm missing something, the main deal with matched bets its covering your bet with another bookie so that you don't make a loss, and then using a newcomers incentive / free bet to increase the gain on that. Assuming the free bet is only offered to new registered users, how can you continue this process without expending all the bookie's available? Or is there just that many offering first-bet incentives? or those offering incentives to existing registrations?
